Note:
1. Please ensure that the spur gear and pinion gear have matching pitches to ensure proper meshing of the teeth.
2. Please verify that the RC motor shaft has a diameter of 3.175mm (1/8").
3. It is recommended to use thread lock on the grub screw to prevent them from falling out.
4. Larger gears will result in higher speeds, while smaller gears provide more torque. For quicker acceleration, opt for a smaller pinion gear with fewer teeth and a larger spur gear with more teeth.
5. A car equipped with more torque will accelerate quickly off the mark and benefit from cooler running temperatures, thereby extending the life of both the motor and ESC.
How to install the pinion gear:
To install the pinion gear, it may be necessary to slightly loosen the motor in order to fit the pinion gear onto the flat portion of the motor shaft. When tightening it back up, ensure there is a small gap between the pinion gear and spur gear, approximately the width of a piece of paper.
